Request to monitor 2138+43 SS Cygni for multiwavelength observations
Abstract:
We are collaborating with astronomers from Lawrence Livermore National Laboratory in the scheduling of multiwavelength simultaneous observations, particularly with the Hubble Space Telescope's Imaging Spectrometer (STIS) and the Rosse X-Ray Timing Explorer (RXTE), and possibly the Extreme Ultraviolet Explorer (EUVE) and ground-based resources, of SS Cyg during outburst. One of the goals is to carry out a multiwavelength search for very small-amplitude and very short-period oscillations of the white dwarf.
Justification:
This campaign is extremely important as it is the last chance for astronomers to observe SS Cygni with HST under this proposal. Timely notification of the onset of the outburst and up-to-the-minute information on the behavior of SS Cyg throughout the outburst are essential for these multiwavelength observations.
